| Abstract: | MnO2 was synthesized by chemical deposition method,then was doped in ordinary active carbon.The electrochemical performance of the MnO2/C electrode samples was studied by cyclic voltammetry,constant current and AC impendence tests.The test results showed that the samples dopped with 20%mass of MnO2 had the best capacitance performance,and its discharge specific capacitance was 255.5 F/g,improved by 49.3% of the undoped carbon electrode.The impedance characteristic of MnO2 doped cabon electrode was improved ... |
